DOOR-BELL.

SPECIFICATION forming part of Letters Patent N 0. 723,908, dated March31, 1903.

' Application filed July 3. 1902. Serial No. 114.233. mamas.)

To all whom-it may concern.-

Be it known that I. CLIFFORD BRADLEY PAGE, a citizen of the UnitedStates, residing at Weiner, in the county of Poinsett and State ofArkansas, have invented certain new and useful Improvements inDoor-Bells; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to door-bells, but" defacing the same and which isdesigned tobe used in connection with' the ordinary knob and bolt.

With these objects in view my invention consists in the novelconstruction and arrangement of the connections and operating means ofthe bell.

My invention also consists in the particu lar combination of parts,which will be first fully described, and afterward specifically pointedout in the appended claims.

Referring to the accompanying drawings, Figure 1 is a plan view of myinvention, showing the bell and door-knobremoved, but their positionindicatedin dotted lines. Fig. 2 is a plan view of my invention inan-operative position. Fig. 3 is a perspective view of my bell-operatingmechanism.

Like numerals of reference indicate the same parts throughout theseveral figures, in which-- 1 is a part of the door-,and2 is thedoor-knob.

3 is the door-knob bolt.

4: is the bell-plate, which is secured to the door by the screws 5.

6 indicates the bell, which is carried on the post 7.

8 is the clapper, which is pivoted on the plate 4 and which is providedwith lug 9.

10 indicates a spring which bears against the arm 11 of the clapper 8.

12 indicates a toothed segment which is se- 5 5 cured to the arm 13 orformed integrally therewith and which is pivoted on the post 7. Pivotedon the arm 13 is a connectinglink 14, provided with a notch 15, whichenters said link at right angles thereto near the lower end thereof andwhich then extends longitudinally a short distance. I

16 is a keeper pivoted to the connectinglink,.having a portion of itslower end cut away, as shown in Figs. 1 and 8.

17 is a crank which is provided with a square opening 18, through whichthe doorknob bolt passes, and which is provided at its outer ends with apin 19, which enters the notch 15 in the connecting-link and which ispassed into the longitudinal portion thereof,

. after which the keeper 16 is swung into position, as shown in Fig. 1.

In operation the knob is turned either way, which raises or lowers theconnecting-link, causing the toothed segment to revolve,wh'ereby theteeth thereof alternately push the lug on the clapper-arm and the springpushes the lug between the teeth, thus rapidly vibrating the clapper andcausing. the same to strike the bell in a manner similar to an electricgong.

.at once apparent, and I have provided for' dis- The simplicity of thisarrangement is engaging the bell-connecting means when it isdesired'notto have the bell ring when the knob ,is turned. To accomplish this, thekeeper is swung'up in position shown in Fig. 3 and the pin on the crankis disengaged from the connecting-link either manually or by.

simply turning the knob to the right, which will carry the pin out ofthe notch.

Having thus described my invention, I do not'wish to be understood aslimiting myself to the exactconstruction as herein set forth, butconsider myself entitled. to all such "changes and modifications thatfall within the limit and scope of my invention as defined by thefollowing claims. t

, What I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In a door-bell, the combination with the door-knob bolt of abell-crank carried thereon, a toothed segment, an arm secured thereto, aconnecting-link between said crank and notch therein, a keeper pivotedto said link and adapted to hold said link in engagement with saidcrank; the whole arranged where by the crank Will disconnect itself fromthe link when the keeper is raised by turning the door-knob.

In testimony whereof I affix my signature :0

in presence of two Witnesses.
